Cobalt complexes appended with p- and m-carboxylates: two unique {Co(3+)-Cd2+} networks and their regioselective and size-selective heterogeneous catalysis.

Co(3+) complexes appended with arylcarboxylate groups act as molecular building blocks to afford {Co(3+)-Cd(2+)} networks. These networks function as the heterogeneous and reusable catalysts for regio- and stereoselective ring opening of epoxides and size-selective cyanation of aldehydes.
